It is definitely unusual. I just read a NYP article that said he had CKD (chronic kidney disease) since 2006. You can have, CKD but not need dialysis or a transplant, it gets watched & monitored by your nephrologist.
He said he got very sick over the summer & went to the doctor when he was told he needed a new kidney. If CKD was controlled/monitored you usually get a catheter put in your chest for urgent dialysis until you either get a long term fistula or peritoneal catheter put in or you get the transplant. I run a surgery center that puts these catheters in every day. You can live for years & years on dialysis. Not a great life since dialysis is 3x a week for 4 hours a day if you don't do the home dialysis. But also a bunch of restrictions on your life.
The article, that was intererviewing him, doesn't make it sound like he had been on dialysis, but he did say he waited at least 2 months after getting symptomatic before seeing a doctor.
The nephrologist I work with will be in on Wednesday. I'll circle back with, hopefully, some clarification.
The article I was reading
Nick Mangold passed away Saturday at 41, less than two weeks after the former Jets center went public with the fact he needed a kidney transplant.
